Platformer Sample - Rope Swing

The RopeSwingState allows the character to simulate hanging on a rope attached to a point. It does this by handling movement in a very similar manner to typical air movement, but with the addition of calling RopeSwingState.ConstrainToRope at the end of the update. This function projects the character velocity to simulate a rope constraint.

This state is transitioned to when the rope input is pressed, and a valid rope attachment point is in range. Rope points are detected with RopeSwingState.DetectRopePoints.

The rope entity is spawned in the state's OnStateEnter. The CharacterRopeSystem handles positioning the rope entity from character to rope attachment point, and destroying the rope when its owning character is not in RopeSwingState anymore.
